In some embodiments, the video processor 110 may include one or more of the components of computational system 400 shown in FIG. 4.

In some embodiments, the system 100 may include a video annotation service 125 or have access to data provided by the video annotation service 125. Video annotation service 125 may receive a video from the video processor 110 and/or the video data storage 105 and annotate the video with video annotations. The video annotation service 125 may output video annotations for an input video. In some embodiments, the video may only be a portion of a video or a clip of interest. The video annotation service 125 may use any number of techniques to annotate the video based on any number of video attributes such as, for example, human annotation of the video.

In some embodiments, the video attributes may include attributes such as, for example, object boundary data, object characteristic data, and/or object event data. The video attributes may vary depending on the object type. The objects, for example, may include humans, animals, cars, bikes, etc.

The object boundary data may include coordinate data describing the boundary of the object within the frame of the video. For example, the object boundary data may specify a plurality of points that when connected form a polygonal shape bounding or roughly bounding the object. In some embodiments, the object boundary data may include pixel data that identifies the pixels representing the object data. Various other data or data types may be used to identify the boundary of an object within the video or a video frame. For example, a polygon (or rectangle) can be used to define the boundary of an object. In this example, the boundary data may include a vector or matrix comprising three or more coordinates corresponding with the indices of the boundary of the object within the video or the video frame.

The object characteristic data may include characteristics that are general to most objects or specific to certain objects. For example, the object characteristic data may include data specifying the objects' size, color, shape, etc. For a human object, the specific object characteristic data may include an estimated sex, gender, age, race, approximate height, approximate weight, hair color, clothing type, accessories, the facial expression of the human, etc. In some embodiments, the accessories may include whether the human is carrying or wearing a box, package, backpack, luggage, briefcase, overnight bag, umbrella, gun, purse, hat, hoody, sunglasses, etc. For a vehicle object, specific object characteristics may include the number of wheels, vehicle type, the number of doors, etc.

In some embodiments, video annotation data may be included in a file separate and/or distinct from the video. For example, the video annotation data may be included in a text file or a metadata file that includes video attribute data and/or data identifying the video. In some embodiments, the video attribute data may include frame data such as, for example, frame timing data. In some embodiments, the video attribute data may vary for each frame of the video. For example, as the video attributes change between frames, the video annotation data may vary accordingly.

In some embodiments, the video annotation service 125 may receive a video from the video processor 110 and/or the video data storage 105, for example, through the network 115 as an input and in exchange may provide video annotation data to the system 100. The video annotation data, for example, may be stored in video data storage 105 or another data storage location such as, for example, another cloud storage location.

FIG. 2 is a flowchart of an example process 200 for training a video annotation machine learning process. One or more steps of the process 200 may be implemented, in some embodiments, by one or more components of system 100 of FIG. 1, such as video processor 110. Although illustrated as discrete blocks, various blocks may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation.

Process 200 may begin at block 205. At block 205 a video clip may be identified from one or more videos such as, for example, videos stored in video data storage 105. For example, the video clip may be a portion of a video that includes an event of interest. The video clip, for example, may include portions or frames of the video before and/or after the video clip in addition to the video clip. In some embodiments, the video clip may include a single frame or multiple frames selected from one or more videos.

In some embodiments, low level events such as, for example, motion detection events may be used to identify the video clip. In some embodiments, a feature detection algorithm may be used to determine that an event has occurred. In some embodiments, the feature description can be determined using a low level detection algorithm.

An event may include any number or type of occurrences captured by a video camera and stored in a video file. An event may include, for example, a person moving through a scene, a car or an object moving through a scene, a particular face entering the scene, a face, a shadow, animals entering the scene, an automobile entering or leaving the scene, etc.

In some embodiments, a feature description of the event can be determined for each event. The feature description, for example, may be determined using a feature detector algorithm such as, for example, SURG, SIFT, GLOH, HOG, Affine shape adaptation, Harris affine, Hessian affine, etc. In some embodiments, the feature description can be determined using a high level detection algorithm. Various other feature detector algorithms may be used. In some embodiments, the feature description may be saved in the video storage location such as, for example, as metadata associated with the video.

At block 210 a first set of object attribute data may be determined from the video clip using machine learning techniques based on machine learning data 230. The dashed lines shown in the flow chart show the flow of data but may not show a step in the process 200. Between blocks 230 and 210, machine learning data may be sent and/or used to determine a first set of object attribute data. The first set of object attribute data may include any type of attribute data.

In some embodiments, the first set of object attribute data may be determined using supervised machine learning techniques. For example, the machine learning data 230 may include a plurality of video clips and a plurality of corresponding object attributes for the plurality of video clips. Support vector machines or decision trees may be used as the type of machine learning functions and may be trained using the machine learning data 230 to produce machine learning functions that can be used to predict the first set of object attribute data.

In some embodiments, the first set of object attribute data may be determined using any type of machine learning technique such as, for example, associated rule learning techniques, artificial neural network techniques, inductive logic programming, support vector machines, decision tree learning, Bayesian networks, reinforcement learning, representation learning, similarity and metric learning, sparse dictionary learning, convolution networks, genetic algorithms, etc.

At block 215 a second set of object attribute data may be received from a video annotation service such as, for example, video annotation service 125. The second set of object attribute data may be received, for example, through network 115. In some embodiments, the second set of object attribute data may be created based on user input.

At block 220 the first set of object attribute data and the second set of object attribute data may be compared. For example, the first set of object attribute data may comprise a matrix or vector of data values and the second set of object attribute data may comprise a matrix or vector of data values. Each of one or more values of the vectors or matrices may be compared.

In some embodiments, the comparison that occurs in block 220 can provide a measure of the quality of the first set of object attribute data. If the second set of object attribute data and the first set of object attribute data are the same, similar, and/or congruent then the comparison can be used to validate the quality of the first set of object attribute data and/or the machine learning process used to determine the first set of object attribute data.

If the second set of object attribute data and the first set of object attribute data are not the same, similar, and/or congruent then the comparison can be used to revise the machine learning process used to determine the first set of object attribute data.

At block 225 the results of the comparison that occurred at block 220 may be used to update the machine learning data 230. In some embodiments, comparison data may be sent to machine learning data 230 and may be used to revise, update, modify, and/or change the algorithm or inferred function that was used to determine the first set of object attribute data. In some embodiments, the updated machine learning data 230 may be used as training data for the machine learning algorithm.

In some embodiments, the first set of object attribute data may be determined using supervised learning techniques. For supervised training purposes, for example, the video clip may be the input to the supervised learning algorithm and the second set of object attribute data may be the desired output for the input data. Using this data and/or other machine learning data 230, the machine learning functions used to determine the first set of object attribute data may or may not be revised. In some embodiments, the comparison data and/or the second set of object attribute data may be added to the machine learning data 230 and the functions used to determine the first set of object attribute data may be continuously updated and/or revised based on the updated machine learning data 230.

In some embodiments, attribute data may be exported. If there is a disagreement between the first set of object attribute data and the second set of object attribute data the exported attribute data may include the second set of object data. In some embodiments, if some or all of the second set of object data is missing, then the data from the first set of object data may be exported.

FIG. 3 is a flowchart of an example process 300 for processing video streams. One or more steps of the process 300 may be implemented, in some embodiments, by one or more components of system 100 of FIG. 1, such as video processor 110. Although illustrated as discrete blocks, various blocks may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation.

Process 300 may begin at block 305. At block 305 the system 100 may receive video streams from a plurality of cameras such as, for example, camera 120, camera 121, and/or camera 122. The video streams, for example, may be received as an mjpeg video stream, h264 video stream, VP8 video stream, MP4, FLV, WebM, ASF, ISMA, flash, HTTP Live Streaming, etc. Various other streaming formats and/or protocols may be used.

In some embodiments, at block 310 the video processor 110 may ensure that the video streams are stored in one or more cloud storage locations such as, for example, video data storage 105. In some embodiments, the video streams may be converted to lower bandwidth video files such as, for example, the video streams may be converted to a video file with a lower resolution, more compression, or a lower frame rate, etc.

At block 315 images from the videos may be extracted for processing. In some embodiments, processing individual video frames rather than a video clip or video file may be less time consuming and/or less resource demanding. Video processor 110 may extract images from the video data storage 105.

In some embodiments, at block 320 the images may be filtered. For example, images that include only the foreground or include a majority of the foreground may be filtered out. As another example, images that do not include an event of interest may also be filtered. Event detection and/or determination may be determined in various ways, some of which are described herein. As another example, poor quality images may be filtered out. These images may include images that are not in focus, have poor lighting or no lighting, etc. In some embodiments, the video processor 110 may filter the images.

In some embodiments, the video processor 110 may execute a function on the image prior to determining whether to filter the image. For example, the video processor 110 may determine whether the image includes at least a portion of an event or whether the image has sufficient quality for processing.

At block 325 the images may be processed. In some embodiments, the images may be processed as described in conjunction with process 200 shown in FIG. 2. Various other processing may occur. For example, the images may be processed to determine a set of object attribute data of one or more objects within the image. As another example, the images may be processed to determine whether to trigger an alarm. As another example, the images may be processed to predict future activity that is likely to occur within a future image. As another example, the images may be processed for camera tracking purposes. As another example, the images may be processed to determine suspicious events occurring within the image. As another example, the images may be processed to synchronize cameras recording videos and/or images of the same scene. As another example, the images may be processed to prepare video summaries. As another example, the images may be processed to filter out false alarm events. In some embodiments, the system 100 may include one or more web servers that may host a website where users can interact with videos stored in the video data storage 105, select videos to view, select videos to monitor using embodiments described in this document, assigning or modifying video attributes, searching for videos and/or video clips of interest, setting alarms based on events occurring within one or more selected video clips, selecting and/or identifying foreground portions of videos, enter feedback, provide object attribute data, select cameras from which to synchronize data, etc. In some embodiments, the website may allow a user to select a camera that they wish to monitor. For example, the user may enter the IP address of the camera, a user name, and/or a password. Once a camera has been identified, for example, the website may allow the user to view video and/or images from the camera within a frame or page being presented by the website. As another example, the website may store the video from the camera in the video data storage 105 and/or the video processor 110 may begin processing the video from the camera to identify events, features, objects, etc. The computational system 400 (or processing unit) illustrated in FIG. 4 can be used to perform and/or control operation of any of the embodiments described herein. For example, the computational system 400 can be used alone or in conjunction with other components. As another example, the computational system 400 can be used to perform any calculation, solve any equation, perform any identification, and/or make any determination described here.

A system for training a video annotation machine learning process, the system comprising: a network; a machine learning database; and a video processor configured to: obtain a video; determine that a predetermined event occurs in the video; identify a first set of object attribute data of the event in the video based on a machine learning process and machine learning data; receive a second set of object attribute data of the event in the video from a user or an exterior source connected to the video processor via the network; compare the first set of object attribute data with the second set of object attribute data; validate the quality of the first set of object attribute data when the first set of object attribute data is determined to be sufficiently similar to the second set of object attribute data; and revise the machine learning process and the machine learning data when the first set of object attribute data is determined not to be sufficiently similar to the second set of object attribute data.
 15. The system of claim 14, wherein the predetermined event comprises a person moving through a scene, a car moving through a scene, an object moving through a scene, a particular face entering a scene, a face, a shadow, one or more animals entering a scene, and an automobile entering or leaving the scene.
 16. The system of claim 14, wherein the user or external source comprises a video annotation service.
 17. The system of claim 14, wherein the first set of object attribute data is saved as metadata associated with the video.
 18. The system of claim 14, wherein the video processor is further configured to: export the first set of object attribute data when the first set of object attribute data is determined to be sufficiently similar to the second set of object attribute data; export the first set of object attribute data when some of the second set of object attribute data is missing; and export the second set of object attribute data when the first set of object attribute data is determined not to be sufficiently similar to the second set of object attribute data.
 19. The system of claim 14, wherein the video is a set of filtered images of an original video.
 20. The system of claim 19, wherein the set of filtered images are images that have been filtered based on primarily including foreground, being of poor quality, being not in focus, and having poor lighting.
